staging: mt7621-dts: update ethernet settings.
The ethernet in mt7621 is now supported by drivers/net/ethernet/mediatek/ which provides support for the integrated switch through DSA. This requires some devicetree changes, and particularly allows a board dts to identify which switch ports are present. The second CPU interface - gmac1 - doesn't work yet, so the device tree information may not be correct. The phy (which is present on the gnubee-pc2) can negotiate and report connection speed etc, but no traffic flows. The gnubee-pc1 has two network ports which are 'black' and 'blue'. There are connected to switch ports 0 and 4 respectively. Signed-off-by: NeilBrown <neil@brown.name> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
